IMPRVEMENT IN FOUL-AIR E'sCAPr-:s FoR WASTE-PIPES.

Specification forming part of Letters Patent No. 124,666, dated March19, 1872.

ters of reference marked thereon` making lpart of this specification, inwhichy Figure l 1s a vertical sectional view of a waste plpe, with myimprovement attached,

secured to a basin. Fig. 2 is a vertical sec tional view of myimprovement, one form 4of valve being shown. Fig. 3 is a verticalsectional view of my improvement, another form of valve being shown.Fig. 4 is a vertical sectional view of my improvement, another form ofvalve being shown.

The object of my invention is by a simple and cheap attachment, arrangedin'connection with the ordinary waste-pipes of abuilding, to furnish themeans whereby the injurious and unhealthy odors, fumes, or gases whichare generated in sewers shall be arrested and carried oii. It isconceded by all who are familiar with malarial diseases and their originor cause that there is no more fruitful source than the one traceabledirectly to this species of impure air, and which is received from thesewer through the waste-pipes and discharged into the apartment, thereto infect with its poisonous miasma thel entire atmosphere. To remedythis, as Ihave said, is the object of my present invention,whichconsists in'securing in a short section of pipe, which Iproposetofurnish to the 'trade as .a manufactured article, a short sleeve, thelower section of which is to serve as a seat for a spring-valve, inconnection or in combination with an auxiliary pipe, which receives andcarries off the foul air and odors thatmay enter the waste-pipe from`the sewer. The section or piece of pipe, with my improvementsattached,is to be inserted at any desired point or position, as asection of the waste-pipe, so that the fall of water through thewaste-pipe shall, by means of its gravity, overcome the tension of thespring, so as to open the valve and allow the water to pass oft', thevalve being automatically closed by the spring the moment the waterceases to run, and, then acting thus compelling it to make its exitthrough the auxiliary or side-pipe into the open .air or some suitablecommon receptacle or dischargepipe.

The construction and yoperation of my invention is as follows: Arepresents the bowl of a wash-stand, the pan of a water-closet, or anyother like household feature, which is now provided with a waste-pipe,B, for the discharge fof water. B is the waste-pipe, and is connected tothe bowl or pan A in the ordinary way. These waste-pipes B are allinvariably connected with the sewer, and through them is constantlyreceived and discharged into the various apartments of the building thepoisonous and healthimpairing gases and odors which the filth in thesewer generates. With my improvement this evil is entirely remedied. Atany desired point, in the ordinary waste pipe, I substitute for a shortsection of the same a piece of pipe, O, with my improvement attached.This short pipe C may be constructed of metal or any other suitablematerial. In this pipe C is secured a cylindrical tube, G',- which is tobe of such thickness as to leave a decided shoulder at c, which is toserve as a seat for the valve. The upper section of this tube isangular, so as to cause it at this point to offer no obstruction,whereby sediment, Src., might be collected and retained. D is a valveand is of such dimensions that, while it shall close the mouth c of thecylindrical tube C',

still its diameter shall be such as to allow of its free movement in thepipe C, so that when depressed by the gravity of the waste-water thereshall be left between the valve and pipe an annular passage forthe'water to pass oii. This valve D -is so secured to a spring, D', asto allow of its direct vertical movement, as shown in Figs. 1, 3, and 4,or it may be .pivoted by a hinge-joint, as shown in Fig. 2. This springD rests and works on an inverted T-shaped rod secured in the pipe, theshort arm clbeing secured across the pipe, and the long arm d' act ingas a guide-stem for the spring. This rod d may be of such length as toextend through the entire length of the spring D', and thence through asmall orifice in the valve, or it` may be shorter than the sprin g, asclearly shown in Fig 2. E is an auxiliary pipe, which is secured to alateral opening, c, of the pipe C', and conveys the odors, or gasesreceived from the sewer to a pipe, E', or other common receptacle. Orthis pipe E may have its outlet through the wall ofthe house. I desireit distinctlyunderstood that about the relative position of thisauxiliary pipe there is nothing definite, its function being to carry o"the odors, fumes, and gases that are now invariably discharged into theapartment; consequently the pipe may be arranged in any manner that willaccomplish this result. Nor is there anything arbitrary about thearrangement of the valve or style of spring shown in connectiontherewith, as any valve and any spring that will permit the valve to beopened through the gravity of the water, and then to automatically closeit, will answer all the purposes which this portion of my invention aimsto accomplish.

From the foregoingfull and detailed description, the working of myimprovement will be readily understood. The tube C', valve D, and springD are arranged inan independent piece of pipe, or if desired, maybe-secured directly' in the waste-pipe B. I prefer the former planbecause it can then be readily manufactured, and, as a inished article,offered to the trade.

Suppose the bowl or pan A to be filled with water that you desire todischarge. Remove the stopper or otherobstruction from the openmg a.,and the waste water will, as usual, flow down the pipe B,passing throughthe tube C. Its gravity,overcon1in g the tension ofthe spring D', willconsequently open the valveD and permit the water to flow over thevalve7 c0ntinuing its course down to the sewer. So soon as the water haspassed oft', the tension of the spring instantly and automaticallydrives the valve against its seat c, securely closing the same, andpreventing all gases, odors, and

fumes generated in the sewer from entering the apartment Where the basinor bowl is situated. These foul gases and odors being arrested by thevalve and having no other outlet, pass off through the pipe E. Practicalexperience has fully attested the entire practicability of theimprovement herein' described.

What I claim as new and 'desire to secure by Letters Patent ot' theUnited -fzltates, is

The waste-pipe B G, tube C', or its equivalent, valve D, spring D', andpipe E, combined and arranged so as to operate substantially asdescribed, as and for the purpose specied.

In testimony whereof I have signed my name to this specification in thepresence of two sub.l

scribing witnesses.
